HEAD COVERING Filed D60. 30, 1964 INVENTOR /'7// TON 5 TOEV ATTORN EY3,292,183 HEAD COVERING Milton Story, 232 Knickerbocker Ave., Hillsdale,NJ. 07642 Filed Dec. 30, 1964, Ser. No. 422,351 1 Claim. (Cl. 2-200) Thepresent invention relates to a head covering and it particularly relatesto a head covering made of thin plastic sheet material. In making headcoverings of thin plastic sheet materials, and particularly those thatmight be used for advertising or publicity purposes in connection withthe sale of merchandise, the election of candidates or nominees, it isdesirable to have a light weight structure, which nevertheless can bereadily made of sheet plastic materials.

It is among the objects of the present invention to make such a lightweight head covering device which will be capable of rapid andinexpensive production on automatic machinery, and which will becomfortable to wear and conveniently carried in ones pocket withoutbreaking or tearing and which will be so joined without stitching thatit will be quite durable and capable of being stretched or forced uponvarious head sizes without rupture.

Another object is to make a simple, inexpensive light weight vinylpolyethylene or polypropylene sheet material which is capable of beingattractively designed and is capable of carrying vivid advertising ordisplay messages for sales of products or for political purposes.

Still further objects and advantages will appear in the more detaileddescription set forth below, it being understood, however, that thismore detailed description is given by way of illustration andexplanation only and not by way of limitation, since various changestherein may be made by those skilled in the art without departing fromthe scope and spirit of the present invention.

In accomplishing the above objects it has been found most satisfactoryto form the cap of a sheet of thin plastic flexible material, such asthin vinyl polymer or thin polyethylene or polypropylene derivatives,and which will not be subject to rupture when stretched or expanded inplacement upon the head. In forming the cap out of the unitary sheet ofmaterial, desirably a top inward fold is provided, with the edges of thefold and of the cap being sealed together incidental to the method ofmanufacture with a quadruple seal adjacent the top of the cap and adouble seal adjacent the lower portion of the cap to balance andreenforce the same.

The inward fold, together with the upper quadruple seal, will givestrength, while the lower structure with the edge seal will givesufficient flexibility and stretchability to enable the cap to bereadily forced down over the varying different head sizes withoutlikelihood of rupture or breaking. Desirably the material used shouldnot be thicker than about 0.001 to 0.005 inch and, if desired, the lowerportion of the cap to be stretched upon the head may be between 0.001 to0.003 inch, while the upper portion, which should be more rigid andusually forms a double fold, may be of 0.005 to 0.015 inch. Generally,the upper portion can have a thickness of two to three times, andsometimes five times the thickness of the lower portion.

Desirably the cap material is made of an opaque thin film of plastic,which has a filler of titanium oxide, zinc oxide or clay, while theouter portion may carry a bright, vivid imprinting of red, blue, orangeor other colors.

With the foregoing and other objects in view, the invention consists ofthe novel construction, combination and arrangement of parts ashereinafter more specifically described, and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificaite ttesate tions can be resorted to which fall within the scope of the claimshereunto appended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views:

FIG. 1 is a top perspective view, showing the cap 0 covering of thepresent invention.

FIG. 2 is a transverse sectional view upon the line 2--2 of FIG. 1.

FIG. 3 is a fragmentary transverse sectional view upon the line 3-3 ofFIG. 1, upon an enlarged scale as compared to FIG. 1.

FIG. 4 is a transverse sectional view upon the line 44 of FIG. 1, uponan enlarged scale as compared to FIG. 1.

FIG. 5 is a vertical transverse fragmentary sectional view upon enlargedscale of the lower edge of the hat of an alternative embodiment.

FIG. 6 is a horizontal transverse fragmentary sectional view of a sideedge of the hat.

FIG. 7 is a fragmentary diagrammatic perspective view taken in sectionof one corner of the device showing reinforcement therein.

Referring to FIGS. 1 to 4, the cap consists of an integral rectangularsheet A of plastic, folded upon a central fold line longitudinally ofsaid sheet, said cap having a front section 15, a rear section 17 and inintermediate section B which is folded inwardly from the top of thefront and rear sections to a depth of generally one-third of thevertical height of said cap to form the inwardly directed portions 12and 13. The front section 15 extends from front edge 10 upwardly to thefold junction 16 and the rear section 17 extends upwardly from rear edge11 to the fold junction 18. The sections 15, 17 and 12, 13 are alljoined together by the edge heat sealing C, which is quadruple in theupper section 19 and double in the lower section 20.

If desired, the lower edges 10 and 11 may be beaded, as indicateddiagrammatically in FIG. 5, with the thickness 15 terminating in acircular or cylindrical bead 22 having a diameter at least twice thethickness of the wall 15. The edges C may also be headed, as indicatedfor example in FIG. 6, with an end bead 23 having about twice thethickness of the thickness of the sections 15 and 17. In respect to theactual thickness of the sheet material in sections 15 and 17 and theirlower portions as indicated at 24 and 25, they may be pressed or soformed that their thickness will be one-half or threequarters of thethickness in the upper portions 26 and 27.

Normally, the sheet to be processed will consist of a continuous sheetor strip having a width of about 10 /2 to 11 /3 inches, with an optimumof 11 inches, which may be cut off into short strips between 9% to 12inches in length, with a preference of 11% inches in length. The inwardfold has a depth of between 1 /2 to 2 inches and desirably is about 1%inches.

The sealing should be along the edge and limited to not over of an inchand desirably to of an inch. The material may be run through the machinecontinuously. To make the lower portions 24 and 25 thinner and moreflexible, they may be pressure rolled before or after the complete capis assembled.

As many changes could be made in the above head covering, and manywidely different embodiments of this invention could be made withoutdeparture from the scope of the claim, it is intended that all mattercontained in the above description shall be interpreted as illustrativeand not in a limiting sense.

The seal at the edges may be made by welding or electronic sealing.

Having now particularly described and ascertained the nature of theinvention, and in what manner the same is to be performed, what isclaimed is:

An expandable stitchless end edge heat sealed thermoplastic film capformed into a single integral elongated folded rectangular sheet ofthermoplastic synthetic film folded upon a central fold linelongitudinally of said sheet, said fold line defining front and rearsections and an intermediate section therebetween, said intermediatesection extending to a depth generally one-third of the height of thecap, heat-sealing means provided along the length of the opposite sideedges of said cap, said heat sealing means securing the side edges saidfront, rear and intermediate sections together on both ends of the capforming a four ply sealed thickness at the upper end edges of the front,rear and intermediate sections and a double seal thickness along theremaining side end edges of said cap.
